Arrived!Wednesday 11:00 & 1:30

Leading-edge Technology on

System zTuesday 3:00



• “Thin” interrupts for CFs• CFCC polled for work to do, so all CF engines were 100% used• So, shared engine CFs had a very limited use case

• A CF always used its entire PR/SM™ timeslice except in DYNDISP=YES mode• Not a great way to implement many/most production CFs

• New CFCC design in CFLEVEL 19 on zEC12 and zBC12 servers along with XES/XCF changes designed to use a more interrupt-driven, hyrbrid approach

• Should allow the use of shared engine coupling facilities in many production environments with acceptable performance

• Intended to lower Parallel Sysplex entry costs by reducing the number of environments for which dedicated coupling facility (CF) engines are needed to achieve good performance

• Also, new set of “thin” interrupts to be used by z/OS• Designed to decrease response time on the average• Help reduce XCF and XES processing overhead and improve performance

when processing asynchronous coupling facility operations and recognizing certain CF events

Three Ways to Compress (and Decompress) on z/OS Software compressionCPU-intensiveMuch slowerData can be inflated on anything supporting the same algorithm

Compression coprocessor-based instructionsDictionary-based compression, generic or tailoredCan be inflated on a System z processorAll compression consumes apparent CP cycles

• Compression done on the coprocessor, but accounted for as CP busy time because the CP is unavailable until the coprocessor is done

z/OS zEnterprise Data Compression Usage and

ConfigurationThursday 1:30


Compression Ratios and Performance* Compression rates will vary with the data…But internal testing shows us ~4X compression for SMF data

At August 2013 SHARE, I said I expected (at least) ~2X compression for Extended Format BSAM/QSAM data, but we had not tested yet

Test numbers are in!For BSAM/QSAM we see up to 4X compression for zEDC

• That’s as much as 2X better than generic or tailored compression

Also, for BSAM/QSAM we see 80% or more CPU time reduction compared to tailored and generic compression

• CPU cost for zEDC is ~0.1sec/GB in testing on a zEC12

* Based on projections and/or measurements completed in a controlled environment. Results may vary by customer based on individual workload, configuration and software levels.

(Note: LZ compression is used in the tape controllers already)



RDMA over Converged Ethernet

Software Delivery*Preventive Service• IBM plans a number of changes to z/OS preventive service ordering, to be made effective 3Q 2014:

•In Shopz, the z/OS "all licensed products" service package type and z/OS Internet delivery service subscriptions will be removed•ServiceLink z/OS ESO packages will be supported only when used to order service for selected FMIDs•z/OS preventive service orders will be based on installed products, not on licensed products

•IBM recommends use of the SMP/E RECEIVE ORDER command•Simplest way to get z/OS service•Can automate service acquisition using local batch scheduling tools•Alternatively, you can use Shopz or the ServiceLink z/OS ESO option

•No changes to corrective service ordering• For more information:

Statements of Direction*




• Enhanced RACF password encryption algorithm planned• Will be designed to provide improved cryptographic strength in RACF password

algorithm processing• Intended to help protect RACF password data in the event that a copy of a RACF

database becomes inadvertently accessible.

• New function is planned for z/OSMF V2.1:• Support for the Microsoft™ Internet Explorer 10 browser• OpenSSH SFTP support for the Incident Log• Integrated management of generated jobs in the Software Management application• Workflow improvements• z/OSMF REST services support for editing and browsing files and data sets.

New news




• z/OS V2.1 is planned to be the last z/OS release to provide software support for several TCP/IP device drivers• IBM recommends migrating to more recent device types, such as OSA-

Express QDIO and HiperSockets™• Planned to be removed:

• Asynchronous Transfer Mode (ATM)• Common Link Access To Workstation (CLAW)• HYPERChannel• Channel Data Link Control (CDLC)• SNALINK (both LU0 and LU6.2)• X.25

• Note: Support for SNA device drivers is not affected.

New news




• IBM intends to remove the SMTPD NJE Mail Gateway and Sendmail mail transports from z/OS Communications Server in the future• If you use the SMTPD NJE Gateway to send mail, IBM recommends you use

the existing CSSMTP SMTP NJE Mail Gateway instead. • The Sendmail client program can also be used to send mail messages

• Replacement function using CSSMTP as the SMTP transport planned; will be designed to not require application programming changes

• No replacement function planned to support using SMTPD or Sendmail as a (SMTP) server for receiving mail for delivery to local TSO/E or z/OS UNIX System Services user mailboxes, or for forwarding mail to other destinations.

New news




Reminders:

• IBM plans to provide support for DFSMSdss to exploit zEDC by the end 3Q14 • Designed for DUMP and RESTORE, and when DFSMShsm uses DFSMSdss

as a data mover• Intended to provide efficient compression with lower CPU overheads than the

processor- and software-based compression methods already available.




Reminders:

• IBM intends to provide exploitation of the Flash Express feature on zEC12 and zBC12 servers with CFLEVEL 19 for certain coupling facility list structures in the first half of 2014• Designed to allow list structure data to be migrated to Flash Express memory as

needed when the consumers of data do not keep pace with its creators• … migrate it back to real memory to be processed later• With WebSphere MQ for z/OS Version 7 (5655-R36), expected to provide significant

buffering against enterprise messaging workload spikes• Potentially allowing several hours' data to be stored without causing interruptions in

processing. • RMF planned to provide measurement data and reporting capabilities




Reminders:• z/OS V2.1 is planned to be the last release to include Version 1 of the Standards

Based Linux Instrumentation for Manageability (SBLIM) CIM client for Java

Version 2 of the SBLIM client, which is designed to be a JSR48-compliant implementation, is included in z/OS V1.13 and in z/OS V2.1

IBM recommends that users of SBLIM Version 1 convert to Version 2

• z/OS V2.1 is planned to be the last release to support the SNMP subagent function of Infoprint Server for communication with PSF-managed printers.

IBM recommends you use the existing functions in z/OS Infoprint Central instead

• IBM intends for z/OS V2.1 to be the last release to support the GATEWAY configuration statement in the TCP/IP profile

Use the BEGINROUTES/ENDROUTES configuration block to replace GATEWAY




Reminders:

• The Cryptographic Support for z/OS V1R12-R13 web deliverable is planned to be the last level of ICSF to support IBM eServer™ zSeries® 800 and 900 (z800, z900) servers

• Future levels of ICSF are planned to require an IBM eServer zSeries 890 and 990 (z890, z990) or later server

Important! This is the same level of ICSF planned to be incorporated in z/OS V2.1, but z/OS V2.1 itself is planned to require an IBM System z9 EC, IBM System z9 BC, or later server

• z/OS V2.1 is planned to be the last release to include the IBM HTTP Server Powered by Domino® (IHS powered by Domino) IBM recommends you use the IBM HTTP Server Powered by Apache, which is available in z/OS

Ported Tools• IBM plans to provide documentation help with migration to IBM HTTP Server Powered by Apache

• z/OS V2.1 is planned to be the last release to support the z/OS BookManager®

Build optional feature




Reminders:• z/OS V1.13 is the final release for which the IBM Configuration Assistant for z/OS

Communications Server tool that runs on Microsoft Windows is provided by IBM Currently an as-is, nonwarranted web download Use the supported z/OSMF Configuration Assistant application instead

• z/OS V1.13 is the last release to support a staged migration for JES2 and JES3. Future releases will require you to migrate to all elements of z/OS at the same time, including JES2, JES3, or both.

• z/OS V1.13 is the last release to support changing the default Language Environment runtime options settings using SMP/E-installable USERMODs. IBM recommends using the CEEPRMxx PARMLIB member to set these options

• With the introduction of the SAF mode authorization in z/OSMF 1.13, IBM intends to withdraw support for Repository mode authorization in a future release. Both modes are being currently supported to allow customers time to migrate to the new authorization mode.



Reminders:

• z/OS V2.1 supports these System z server models and later server models:• IBM System z9 Enterprise Class and IBM System z9 Business Class• IBM System z10 Enterprise Class (z10 EC™) and IBM System z10 Business

Class™ (z10 BC™)• IBM zEnterprise 196 (z196) and IBM zEnterprise 114 (z114)• IBM zEnterprise EC12 (zEC12) and IBM zEnterprise BC12 (zBC12)

• z/OS Version 2 requires these DASD control units, or later ones:• 3990 Model 3 or 3990 Model 6• 9393• 2105• 2107• 2421, 2422, 2423, or 2424
